St Maarten: Orient Bay? Tour BOTH sides?

[catjammies]

Looking at excursions here:

Both the French Beach Rendezvous
OR
Afternoon Beach Bash at the same place.

WHAT's THE DIFFERENCE?????????

OR

Should we just do the Under 2 Flags Tour? ---
we're Fair skinned --- & have kids.
but the Caribbean water is Sooooooooooooooo pretty.


What to do???

Specifically - can you explain the difference betw. the 2 diff. Orient Bay tours????
